College Algebra vs Trig/Pre-Calc in 11th Grade [prospective business major]

Hmmm…ok that makes sense. He always gets a high B in Math but can never get it to an A. So somewhere around an 88/89 every quarter. Our school only offers Trig/pre Calc (regular and Honors) and then AP Calc AB and BC. No regular Calc. I will talk to the Math teachers this week to try to figure out a plan. Its a large public high school so not a ton of support in this department.
